[DebtDeflation]

Most of the well known historical Ponzis started out as legitimate investment funds. Then the fund manager started commingling funds and taking risks with customer money in an attempt to boost returns. Inevitably, there was a loss, and at that point the Ponzi component (paying existing investors with new investor's funds) got started, with the intent being to only do it until they could catch up on the losses and then return to being legitimate. The "catch up" never happens and eventually all new inflows are going to pay out existing investors. It blows up when outflows exceed inflows. In the case of FTX/Alameda it seems the blowup just happened earlier than usual, before they could reach "Full Ponzi".

The blowup happened because CZ acres on the leaked balance sheet. It might have been years before FTX found out otherwise.
